Abstract: A method and a device for measuring the characteristics of a sample by spectral analysis. According to the method, the characteristics are calculated from the spectral data obtained by the spectral analysis, using a calibration model that has been established on the basis of reference samples. In order to improve the stability of the measuring process, an additional calculation of the characteristics (16) of the samples (1) takes place, using at least one additional calibration model (14) that has been established on the basis of additional reference samples (1″). Deviations between the characteristics (12, 16) calculated by the respective calibration models (11, 14) are determined and output.
